[xsl] Seek a simple XPath 2.0 expression to return union xs: simpleType containing xs:string

Hi Folks, I seek an XPath 2.0 expression that returns all XML Schema simpleTypes containing a union with memberTypes containing the XML Schema string type. (Phew! Did you catch all that?) So, the XPath should return the union simpleType in this schema: ----------------------------------------------------------------------------- ----- <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"> <xs:simpleType name="test"> <xs:union memberTypes="xs:int xs:string" /> </xs:simpleType> </xs:schema> ----------------------------------------------------------------------------- ----- The XPath should not return the union simpleType in this schema: ----------------------------------------------------------------------------- ----- <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"> <xs:simpleType name="test"> <xs:union memberTypes="xs:int string"/> </xs:simpleType> <xs:simpleType name="string"> <xs:restriction base="xs:string" /> </xs:simpleType> </xs:schema> ----------------------------------------------------------------------------- ----- I created a horrendously complex XPath 2.0 expression. I think it works (it's so complex, I'm not sure). Is there a simpler XPath 2.0 expression to solve this problem? Here's the ugly XPath 2.0 expression that I created: //xs:simpleType[xs:union[@memberTypes] [exists(index-of(for $here in ., $i in tokenize(@memberTypes, '\s+') return namespace-uri-from-QName(resolve-QName($i, $here)) eq 'http://www.w3.org/2001/XMLSchema' and local-name-from-QName(resolve-QName($i, $here)) eq 'string', true()))]] /Roger
